The present invention relates to improvements in root, more particularly, potato-harvesting-machines adapted to be attached to a tractor and having a power take-oi driven spinner.

Potato harvesters having a running gear and being power take-off driven of conventional con.

struction are laterally movable and are very long whereby turning and maneuvering is made dinicult and the share is inaccurately guided particularly when operating on a hill Motor driven cultivators are known, the frame of which is directly movably connected with the rear axle of the tractor. In this case the tractor carries the teta! weight of the working apparatus whereby objectionable vibrations are produced which cause great wear and tear on the lifting devices.

It is an object of the present invention to provide a harvesting machine of such construction as to avoid the above-mentioned shortcomings. According to the present invention the frame of `the harvesting apparatus. proper is directly articframe of the harvester comprises two parts which are movably connected with. one another; for transport purposes said two parts form an angle. One part of the two-piece frame carries a latch member which is adapted to engage a lock memberin the otherpart and can be disengaged from said lock member by means of a lever for lifting the joint into rest or transport position in which position said two parts form an angle. Y

Further and other objects of the present invention4 will be hereinafter set forth in the accompanying specification and shown in the-drawings -.which, by way of illustration, show what I`now consider to be a preferred embodiment of my invention. y y

In the drawings which show by way of example the embodiment of my invention in a one row potato harvester Figure 1 is a schematic side view of vester in operating position, l

Figure 2 is a schematic side view of the har; vester in rest or transport position,

Figures 4, and 6 show modications of the According to the present invention the f Aktiengesellschaft,

(ci. 55ans) mechanism for changing the harvester from rest position to operating position and vice versa.

Like parts are designated by like numerals in all figures of the drawings.

The frame oi the harvester is made up of carrying members I and 2 which are lsecure against twisting and which are movably interconnected by means of a horizontal bolt 3; the front end of the frame carries a connecting rail 4 which is articulated by means of lashes 5 and 6 and the horizontal bolt 1 to the front end member I. Rail 4 is removably connected with a corresponding rail 8 ofthe (tractor-Sand vis rigidly connected therewith in a horizontal plane. The position of rail I with respect to rail 8 and the tractor can be changed; for this purpose a plurality of surplus holes 28 are provided in rail member 8 for ac-.

commodating bolts 29 which interconnect rails 4 and 8. The rear part 2 of the frame of the harvester which carriesl the harvesting devices proper, namely the share 21 and the spinner 2|, is supported by means of the support Wheel I0. The

fore end of the carrying member 2 is provided with a segment I2 having a locking surface 25 which is adapted to receive the end of one arm of the two arm latch lever i3 which lever is swingably -connected with the forward carrying member I and pulled into a position to engage segment I2 and surface 25 bymeans of a spring 30. Arm 26 of latch lever I3 is abuttingly engaged by a lever I4 which is fulcrumed to member I and adapted to actuate the latch member I 3. The foreward end of the carrying or frame member 2 is provided with a boss 22 having a threaded hole through which the threaded adjusting spindle I I extends. with a hand wheel 3| and the lower end with anr abutment 32 which is adapted to abuttingly engage the front carrying member I. 'I'he axle I9 of the spinner 2| carries a wheel 20 having an inv ternal gear which is in mesh 'with the gear wheel Il connected to the drive shaft I1 which shaft is connected by means of a universal joint 33 with the intermediate shaft I6; the latter is adapted to be connected with the powerv take-oil' I5 of the tractor 9.

In 'operating condition of the harvester shown in Figs. 1- and 3, abutment 32 rests on the front carrying member I and limits the operating depth of the share 21 whichdepth can be adjusted by manipulation of spindle or rather wheel 3|; due to their` weight and the action of the share on the ground engagement of abutment 32 and member is assured and relative position of mem- The upper end of spindle l is provided `from the position of the tractor. pren 'on the share the harvester can fold up- According to Figure 4, theadiustable abutment member I. 'different configuration in order to be pulled by and upon counterclockwise movement of lever Il. If, asshown in' Fig. 6,' lever Il shown in Fig. 2 is accomplished by pulling lever Il against a projection 2l connected with member I whereby frame part I is swung upward c about bolt 1. 'I'he frame I, 2- thereby folds upward in the joint 3 and member 2 swings about axle 24 of the support wheel I0 which, at the the swinging motion of said frame.

same time, is moved .closer toward the tractor.

Latch member Il, due to the vaction of spring 30,

snaps-into engagement with. the locking surface 25 of segment I2; arm 2l' of the latch member engages thereby lever Il.

In order to `change the harvester from rest into operating position, lever Il must be moved baci:- `ward and counterclockwise; latch I3 is thereby -also moved counterclockwise against vthe action `of-spring and lock part I2, 25 of member 2 bolt I Lifting of the harvester into the rest position aasases said pin member being adapted to secure folding of said frame and-"swinging of said harvester relatively to the tractor ina substantially vertical plane and to prevent movement of said harvester 5 relatively to the tractor in'a plane parallel to the ground, and a support wheel laterally swingably andvertically unmovably connected with the other of said frame members for supporting the rear end of said folding frame and limiting 2.
